Title: Hydraulic circuit for construction equipment
Inventor: SHIMADA YOSHIYUKI
IPC: F15B11/16
Filed: 2000-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent extreme speed down of a main body side actuator by supplying sufficient hydraulic fluid flow amount to the main body actuator even when a pressure of an attachment circuit of a hydraulic excavator gets close to a relief pressure. SOLUTION: In an interlocking operation of an attachment of a hydraulic excavator and other main body side actuator, when pressure of an independent attachment circuit 37 controlling an attachment gets close to a relief pressure, a controller 71 detecting pressure increase condition thereof by a pressure sensor 66 switches an electromagnetic selector valve 68 to a passage connection condition and prioritized flow amount dividing from a pressure correction type flow divider valve 38 to an external passage 67 flows out to a tank 39 via the electromagnetic selector valve 68.

IPC: G02F1/133
Filed: 2000-09-13
Abstract: PROBLEM TO BE SOLVED: To realize uniform picture display by preventing the occurrence of display unevenness even in the case of performing unique picture display like checkers. SOLUTION: In this display device, writing intervals among signal lines S0 and S1, signal lines S1 and S2,..., signal lines Sn-1 and Sn are uniform, but the interval between signal lines Sn and S0 is longer than other intervals. Moreover, it is on the signal line S0 that the writing of a signal whose polarity is inverted is performed at first. As a result, the writing characteristic of the signal line S0 is made different from that of other signal lines. In this device, a dummy signal line S0 is arranged in an adjacent relation with the analog switch SW1 connected to the signal line S1 of the first stage and the opening and closing of the dummy analog switch SW0 connected to the dummy signal line S0 is controlled by a dummy shift register SR0. Thus, writing characteristics become uniform and the uniform picture display is possible.
